The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
First it should be noted that, in explanation of the present utility model, the restriction vocabulary of use, if " first ", " second " are only for ease of clearly narrating content of the present utility model, does not limit scope of the present utility model.
With reference to Fig. 2 to Fig. 4, the air chamber support of a kind of specific embodiment of the utility model comprises rack body 10 and is vertically connected at respectively base 20 and the air chamber plate holder 30 at these rack body 10 edges, wherein, described base 20 is for being connected to driving axle housing, and air chamber plate holder 30 is for connecting and supporting compressed air brake cylinder.According to the position relationship that packs vehicle into, two plate faces of described rack body 10 are defined as respectively to medial surface 11 and lateral surface 12, and usually, medial surface 11 fingers are towards the plate face of longitudinal center's axis of vehicle, otherwise are lateral surface 12.Described air chamber plate holder 30 is extended from described rack body 10 edges towards the direction of described medial surface 11 place one sides, and perpendicular to described rack body 10.On described rack body 10, be formed with the camshaft supported hole 13 that outside side 12 directions are extended, for the camshaft of supporting cam wheel formula drg.Particularly importantly, described rack body 10 is formed as to the platy structure of described medial surface 11 direction bendings, and as shown in Figure 3, the bending direction of rack body 10 is consistent with the bearing of trend of air chamber plate holder 30.Than straight tabular rack body, in bending structure, distribution of stress is more even, has better resistance to shock.
Particularly, described air chamber plate holder 30 can comprise the first spaced installation portion 31 and the second installation portion 32.For avoiding air chamber plate holder 30 and rack body 10 junctions to occur that crack affects air chamber support intensity, the root junction of described the first installation portion 31 and the second installation portion 32 has been preferably formed as fillet.And described the first installation portion 31 and described the second installation portion 32 can lay respectively at end and the middle part of described rack body 10 1 lateral edges, guarantee that compressed air brake cylinder has enough installing spaces on the one hand, make on the other hand force transmission to rack body 10.
As the air chamber support of a kind of preferred implementation of the utility model, can make to be formed with the first reinforced rib 41 between rack body 10 and described the first installation portion 31, between described rack body 10 and described the second installation portion 32, be formed with the second reinforced rib 42.Because rack body 10 is larger near a side compression chord of its medial surface 11, and near camshaft supported hole 13, distribution of material is more, bearing capacity is stronger, can make described the first reinforced rib 41 and the second reinforced rib 42 be formed on the described medial surface 11 of described rack body 10, and extend near described camshaft supported hole 13 places.Replace traditional deep floor perpendicular to air chamber plate holder 30 with the reinforced rib extending to camshaft supported hole 13, more meet the bang path of power in rack body 10.
For reducing air chamber support weight, make driving axle housing and even vehicle produce less stress, on described rack body 10, can be formed with the first through hole 14, this first through hole 14 is between described the first reinforced rib 41 and described the second reinforced rib 42.Described the first through hole 14, between two reinforced ribs, neither can produce considerable influence to the transmission of power, guarantees the intensity of air chamber support, also has the material of saving, reduces the advantages such as vehicle oil consumption.Further, in described the first through hole 14, be formed with to projecting inward annular strengthening rib 15.
Similar with the formation principle of above-mentioned the first through hole 14, the side near described base 20 on described rack body 10 also can be formed with the second through hole 16.
Corresponding to above-mentioned the second through hole 16, and in conjunction with the view of the base 20 shown in Fig. 4, described base 20 can be formed as having " V " font structure on two free ends 21 and a top 22, and two described free ends 21 and described top 22 lay respectively at described medial surface 11 directions and described lateral surface 12 directions of described rack body 10.It should be noted that, said structure is not limited to strict " V " font, can be also " Y-shaped " etc., as long as it can be formed with part of hollow and enough for being connected to the space of driving axle housing, all belongs to design scope of the present utility model.Wherein, the part of hollow can further reduce the quality of support entirety; Free end 21 and top 22 lay respectively at the both sides of rack body 10, can make base 20 more even with the connection structure distribution of force of driving axle housing.
In described air chamber plate holder 30, be formed with the air chamber mounting hole 33 for compressed air brake cylinder is installed, two described free ends 21 and the described top 22 of described base 20 are formed with respectively the support mounting hole 23 for being connected to driving axle housing.
As the air chamber support of a kind of comparatively preferred implementation of the utility model, the angle for being connected between the second attachment face 34 of air chamber for being connected to the first attachment face 24 of vehicle and described stent bearing plank 30 of described base 20 can be 90 °-135 °, is preferably 109 °.
In addition, the utility model also provides a kind of vehicle, and this vehicle comprises the brake system with cam type brake, and this brake system comprises the compressed air brake cylinder connecting by air chamber support of the present utility model.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can combine by any suitable mode.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible array modes.
In addition, also can carry out combination in any between various embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
